CANDLE-END-FORMING MACHINE.

Specification of Letters Patent.

Patented Nov. 23, 1909.-

To all whom-it may concern:

lVhiting, in the county of Lake and State of- Indiana, have invented a new and useful Improvement in Candle-End-Forming Machines, of which the following is a specification.

My invention relates to improvement in machines used for forming flanges on candles adjacent to their lower or butt-ends, and for so shaping these ends below the flanges as to permit the candle to be firmly seated in sockets of varying diameters, in Candlesticks, Candelabras, and the like.

All candles of one size are molded with their lower ends of uniform diameter but unless a holder is rovided with a socket of a corresponding iameter, "a candle when laced for use therein fails to be properly seated, with the result that the candle tilts or leans, causing it to burn unevenly and to present an unp easing appearance whichis especially apparent when a number of candles are grouped together as in a candelabra. On account of the varying diameters, and the irregularities of'sockets in Candlesticks, candelabras and like holders, it has become customary for manufacturers to so form the lower ends of certain varieties of candles (after molding), as to permit of their being crowded into difierent sized sockets-until proper seats are given to the candles tothese candles expeditiously and uniformly.

Referring to the accompanying drawings:-Figure 1 is a view in rear elevation of my improved machine; Fig. 2 is a plan view of the same; F ig. 3 is a plan View of the slide for actuating the movablemolde members; Fig. 4, a view of the machine in end elevation, as viewed from the left-hand side of Fig. 1; Fig. 5 is a transversesection atlinen, Fig. 2, showing-the mold open with the movable mold-members at'their extreme outer position, and Fig. 6 is a similar view,

showing the mold closedwith the -moldmembers at their innermost limitiofmo'vement; F i -7 is a broken sectionon line 7, Fig.2; Fig. 8 is a section on line 8, Fig. 2; Fig. 9 is a view in elevation of a candle as it comes from the mold and before its end has been flanged, and Fig.10' is a similar view of the same after its end has been formed by means of my improved machine.v

Abed 11 is supported on legs 12, and two similar mold members 13 adapted to be moved toward and from each other transversely .of the bed are supported thereon near one end-betweeneguides 14. A slideplate 15- provided with cam-slots 16 near one end and witha longitudinal slot 17 (Fig. 3.), occupies a position centrally ofthe bed to be moved lengthwise thereon toactuate the mold-members 13. These latter, carry pins 18-in'en agement. with the slots-.16, so

that as the p ate. is moved: tothe right in Fig. 2 the members 13 are drawn-to ether as shown in Fig. 6, and .when the p ate is -moved in the contrary direction, the memhers-13 are forced apart as shown inFig. 5, corresponding with the position they are shown tooccupy' in Fig. 2. Only one of these pins 18' is shown and by dotted repre ,sentatlon in Fi 8. A head. 19 provided with a removab esocket-piece 20 is adjustably secured to the plate 15 by a bolt 21 passingthrou h the slot 17-, so that asthe plate is movback and forth the headis carried withit to slide between-bearings. 22, secured to-the bedon'oppositesidesof, and

adjacent to the slide-plate 15. This plate. is provided witha notch 23 at one end anda stop 24 of the samewidth as the llOtClLdS bolted toithe bed and confines. a projecting buffer. 25 which is. engaged by. the .slide in.

its return movement, or toward the left-hand in Fig. 8, to absorb the shock and prevent jar to-the machine For actuating the slide-plate, ashaft 26'is hung in-bearings 27 Securedto the legs 12, and a foot-treadle 28 held' by a set-screw to the shaft, depends therefrom into position rto be swun in. a backward direction by the foot of t e' operatortq rock the shaft in the direction indicated by the arrow at the end of the 'treadle in. Fig. 4,; Upon release of. the tread-lethe shaft is rocked in the reverse direction to return the treadle to its initial position, by a weight 29 mounted on the end of an arm 30 projecting from the shaft to which it is he d by a set-screw. Adjacent .to the treadle is secured on the shaft an arm head 39is bolted to the bed adjacent to the movable mold-members 13, and a stationary mold-piece or die 40 is held therein by means of a set screw 41 (Fig.8). Before tightening the set-screw 41, the die is adjusted into close contact with the mold-members 13, by means of the threaded sleeve 42 which latter is'then secured a ainst accidental turning by a jam-nut 43. Within the sleeve is mounted a dislodging-plunger 44, provided on its inner end with a head 45 and on its outer end with a head 46. The lunger is limited in its outward movement. y the engagement of the head 45 with the end of a recess 47 in the sleeve, which brings the head just flush with the inner end of the sleeve 42, and the movement of the plunger in the reverse direction is limited by the enga ement of the head 46 with a stop 48 in the orm of .a second sleeve. This sleeve,-like the one 42, is

capable of adjustment in a similar manner,

and when properly positioned is held against accidental turning y a jam-nut 49.

A lever 50 with its upper end in line with the plunger and passing through a slot 57 in the bed, is fulcrumed at its lower end toa bracket 52 depending from the bed '11. A rod 53 threaded at one end is pivotally attached at its opposite end at '54 to this lever, "from-which it extends along the under 7 side of the bed and passes loosely through a lug 55 projecting from the plate 15 through a slot 56 in the bed. Upon this rod at one side of the lug is a nut 57 so that as the slideplate is moved to the left (Fig. 8), the lug I impinges against the nut to slide the plunger to the position shown in this figure,

through themedium of the rod 53 and 1e:

ver 50.v I

The candle shown in Fig. 10 1s provided 55 with an ornamental flange or collar 58 and a corrugated tapering end 59. In order'to form the collar and end shown on a candle in the condition represented in Fig. 9, which is that in which it leaves the candle-mold,

' each mold-member is provided with a semicylindrical recess 60 in its face of a form to corres ond with the contour of the flange 58, and the dieor mold 40 is provided with an inwardly tapering socket 61 properly fluted to produce the shape and corrugations of the end 59. With the mold-members together in closed condition in the position shown in Fig. 6, they form, in con unction with the die 40, a complete mold, so that when the end of the candle is upset within, the material of the candle is crowded-out to fill the mold producing the collar and end shown in Fig. 10. i

The operation is as follows: The head 19 is properly adjusted upon the plate 15 according to the'length of candle to be finished and with the parts in their normal position shown in the drawings, the operatorjenters the tip of a candle 62in thesocket-member 20 (Fig. 1), and-rests the candle upon the support 63 secured to the slide 15, and the support 64 attached to the head 19'. These supports position the. candle in alinement with the mold-members 13. The operator then actuates the treadle which through its connections with the slide-plate '15 carrying the head 19, forces the candle into the mold to crowd the lunger'44 outwardly and to upset the end of the candle in the mold. to form the flange and tapering corrugated end. The initial movement of the slide in this direction forces the mold-members 13 together priorto the upsetting of the end of the candle. When the candle end has thus been formedto finish the candle, the operator releases the treadle whereupon the weight acts to rock the shaft and return the treadle to its-normal position. The initial moyement in this direction through the medium of the s1ide15 separates the movable mold-members tothe position shown in Fig. 5, and when the lug 55 in sliding on the rod 53 contacts the nut 57, the lever 50 is caused to strike the head 46 of the plunger, forcing the candle from the socket 61 of the die 40, and upon return of the slide to the position shown in Fig. 8, against the buffer 25, the

candle is removed by the operator, to be replaced by another for repeating upon it the described operation of the machine. It should be stated that the socket-member 20 is preferably made of soft material such as leather or rubber and provided with a socket of just the shape of the tip of the-candle in order to form acomplete bearin for the candle at this point and prevent chipping or marring its end. I,

What I claimias new and desire to secure by Letters Patent-'is 1.
